[v3,0/2] Improve PLIC functionality

Message

Atish Patra March 2, 2020, 11:11 p.m. UTC

This series adds following PLIC functionalities

1. Enable/disable interrupts only on cpu online/offline events.
2. Support multiple PLIC nodes in the device tree. This is required
for multi-socket platforms such as OmniXtend.

The 1st patch was originally part of the CPU hotplug series[1]. It is added to
this series now to keep all the PLIC related changes together.

Rebased on top of 5.6-rc4.
